  In the example of FIG. 1A, the storage unit 108 is provided inside the portable terminal 101, but the present invention is not limited to this and may be detachable. Further, the configuration of the tuner unit 104, the display unit 106, and the like may be provided separately from the portable terminal 101 and connected by wire or wirelessly.

  FIG. 1B is a block diagram illustrating an example of a configuration of a broadcast receiving device having a recording function. The broadcast receiving device 111 is an information processing apparatus such as a television or PC (Personal Computer) capable of receiving terrestrial digital broadcasts, for example.

  The input unit 113 includes a key, a touch panel, and the like, and is used by a user to input instructions and information. The tuner unit 114 receives broadcast data including program data and program information of a plurality of channels. In this example, broadcast data of a plurality of channels is received by one tuner unit 114, but a separate tuner unit may be provided for each channel. Further, instead of the input unit 113 or in addition to the input unit 113, a signal receiving unit such as an infrared receiving unit may be provided, and the user may input an instruction or the like using a remote control device.

  The decoding unit 115 converts the compressed program data into data that can be displayed on the display unit 116 or an external display device. The display unit 116 is composed of a liquid crystal monitor or the like, and displays moving images, still image data, messages to the user, and the like. Instead of the display unit 116, an output unit that outputs the data decoded by the decoding unit 115 to an external display device may be provided. In addition, an output unit is provided in addition to the display unit 116, and for example, program data is output to the output unit, and program information is output to the display unit 116. good. For example, when the display screen of the display unit 116 is small, the user can view the program on a large screen by outputting the program data to a display device having a large display screen via the output unit.

  The control unit 117 is, for example, a CPU, and controls each component of the broadcast receiving device 111. The first storage unit 118 is a so-called ring buffer, and repeatedly records broadcast data of a predetermined time or a predetermined capacity received by the tuner unit 114. For example, when the number of channels is six, for example, the capacity of the first storage unit 118 is such that a broadcast wave with a data transmission rate of 1 Mbps (BitPerSec) for each channel can be stored for two hours for each channel. It is assumed that 2 MBps * 2h * 6ch = 10 GB. The second storage unit 119 records, for example, broadcast data of a channel instructed to be recorded from the input unit 113 or the portable terminal 101, a control program executed by the control unit 117, and the like, for example, having a storage capacity of 1 TByte. Have. In this example, the first storage unit 118 and the second storage unit 119 are provided separately, but the present invention is not limited to this, and one memory may be used.

  In addition, the data transmission / reception units 102 and 112 shown in FIG. 1 are not limited to those that perform wireless communication, and either one or both of them can be used for wired communication such as high-speed power line carrier communication (PLC (Power Line Communications)). It may be what performs. Moreover, you may make it provide both the transmission / reception part which performs wireless communication and wire communication.

  FIG. 2 is a schematic diagram for explaining a method for recording broadcast data in the first storage unit 118 of the broadcast receiving device 111.

  The broadcast wave received by the tuner unit 114 is filtered into broadcast data of each channel and input to the first storage unit 118 via the control unit 117. The first storage unit 118 is divided into a plurality of memories such as a first channel storage memory 201 and an Nth channel storage memory 211. In the example of FIG. 2, the program data of the first channel is stored in the area 203 of the storage memory 201, and the program data of the Nth channel is stored in the areas 213 and 215 of the storage memory 211.

  In addition, the control unit 117 extracts program information from the broadcast data of each channel output from the tuner unit 114 and inputs the program information to the first storage unit 118. The first storage unit 118 stores the program information in the storage memory for each channel in the same manner as the program data. For example, the program information of the first channel is stored in the header area 202 of the storage memory 201, and the program information of the second channel is stored in the header area 212 and the header area 214 of the memory 211.

  Here, the program information is, for example, the EIT information (Event Information) described in the Ministry of Internal Affairs and Communications Ordinance and Notification and the Radio Industry Association (ARIB) Operation Regulations “Program Sequence Information Used for Digital Broadcasting” (ARIB STD-B10, ARIB TR-B14) Table: EPG (Electronic Program Guide) using an event information table) or other information may be used. In the example of FIG. 2, the program start time is stored as program information in the header area 202 or the like, but the present invention is not limited to this, and the program identification code is changed to the start time or in addition to the start time. Or end time, title, program summary, etc. may be stored. Note that a clock may be provided in the broadcast receiving device 111, and the time measured by this clock may be stored instead of or in addition to the start time stored in the header area.

  In the example of FIG. 2, program data and program information of one program are stored in the storage memory 201, and two program data and program information are recorded in the storage memory 211. Here, the storage memory 201 and the like are each configured as a ring buffer, and when recording exceeding BOTTOM, the recorded data stored in TOP is overwritten and stored.

  FIG. 3 is a flowchart showing a control method in the case where a recording instruction is given from the mobile terminal 101 to the broadcast receiving device 111.

  When a program of a channel selected from a plurality of channels by the user using the input unit 103 is viewed on the mobile terminal 101 (S301), if there is a program desired to be viewed from the beginning of the program, the input unit 103 Is used to input a recording instruction (S302). When the recording instruction is input, the control unit 107 extracts channel information and start time information from the program information (S303), and reads out device identification information indicating the broadcast receiving device 111 that requests the recording instruction from the storage unit 108 ( S304). Here, the device identification information is unique information assigned to the broadcast receiving device 111, such as a telephone number or an IP address. The device identification information is previously input by the user using the input unit 103 and stored in the storage unit 108, for example. When a recording instruction is input from the user in S302, the name of the broadcast receiving device in which the device identification information is stored in the storage unit 108 may be displayed on the display unit 106, and user confirmation may be requested. . In addition, it is desirable to be able to store device identification information of a plurality of broadcast receiving devices, and display a list of broadcast receiving devices on the display unit 106 when a recording instruction is input so that the user can select.

  The mobile terminal 101 reads the device identification information of the broadcast receiving device 111 that is the recording instruction destination, and then records the recording instruction information including the channel information and the start time information into the terminal identification information such as the phone number and mail address of the mobile terminal 101 At the same time, the data is transmitted to the broadcast receiving device 111 via the data transmitting / receiving unit 102 (S305).

  The broadcast receiving device 111 receives the terminal identification information and the recording instruction information through the data transmitting / receiving unit 112 (S306). The control unit 117 starts storing the program data of the channel corresponding to the received channel information in the second storage unit 119, and stores a storage start address indicating the position where the storage is started (S307). At this time, it is desirable to control to stop storing new program data in the storage memory 201. This is because the program start data stored after the recording instruction is input may be erased by overwriting, and the program data currently being broadcast is stored in the second storage unit 119.

  FIG. 4 is a schematic diagram illustrating a recording method in the first storage unit 118 and the second storage unit 119 when a recording instruction is given to the broadcast receiving device 111. Here, a case where a recording instruction for the first channel is instructed is shown. The second storage unit 119 has a program data file and a management file. In the example of FIG. 4, an area 401 of the program data file indicates an area where the program data started to be stored in S307 is stored, and an area 405 of the management file indicates a storage start address of the program data stored in the area 401. Indicates a stored area.

  After storing the program data in the second storage unit 119 (S307), the control unit 117 searches whether the program data from the beginning of the program is stored in the first storage unit 118 (S308). The search is performed, for example, by comparing the start time stored in the header area 202 with the start time included in the reception instruction information. If the start time stored in the header area 202 is before the start time included in the reception instruction information, it is determined that the program data has been stored from the beginning of the program. If no header area is stored, it is determined that the beginning of the program has been erased by overwriting.

  When the program data from the beginning of the program is stored, the data transmission / reception unit 112 notifies the recording success using the received terminal identification information (S309). If there is no program data from the beginning of the program, a recording failure is notified (S310).

  When the portable terminal 101 receives a recording success or failure notification via the data transmission / reception unit 102 (S311), the portable terminal 101 displays a message indicating that the recording has succeeded or failed on the display unit 106 (S312).

  When the program data from the beginning of the program is stored in the first storage unit 118, the broadcast receiving device 111 detects the data size of the program data (S313). Freeing up the capacity for the detected data size, continuing to store the program being broadcast, starting copying the program data stored in the first storage unit 118 to the second storage unit 119, and copying the program The storage start address of the data and the program data being broadcast is stored in the management file (S314). In FIG. 4, an area 402 is a storage area for copied program data, and an area 403 is a storage area for program data being broadcast. The storage start addresses of the copied program data and the program data being broadcast are stored in areas 406 and 407, respectively.

  Then, the flag for identifying the program data stored by the recording instruction from the portable terminal 101 and the program information of the stored program are stored in the management file areas 408 and 409, respectively (S315). The second storage unit 119 may store program data stored by the recording instruction input from the input unit 113 of the broadcast receiving device 111 in addition to the program data stored by the recording instruction from the mobile terminal 101. Therefore, by storing the flag, the program data instructed to be recorded from the mobile terminal 101 can be easily identified. In the example shown in FIG. 4, header information is stored in the area 404, and management data 410, 420 for each program is configured including this header information. In the header information, for example, data indicating the order of reading the storage start addresses stored in the areas 405, 406, and 407 is stored.

  The broadcast receiving device 111 stops storing the program data when the end time of the program extracted from the received program information is reached (S316). Note that the end time is not limited to that extracted from the program information, but transmitted from the mobile terminal 101. You may use what was done. Further, the recording stop instruction information transmitted from the mobile terminal 101 may be stopped when the recording stop instruction information transmitted from the mobile terminal 101 is received.

  By controlling as described above, even when the user is out, the program data from the beginning of the program can be stored in the broadcast receiving device 111 using the mobile terminal 101.

  In the example described above, the tuner unit 114 of the broadcast receiving device 111 receives all channels, and the first storage unit 118 stores program data of all channels for a predetermined time. However, the present invention is not limited to this. For example, the user selects in advance a plurality of channels that are frequently viewed, the tuner unit 114 receives the channels selected by the user, and the first storage unit 118 stores the program data of the selected channels. Also good. As a result, depending on the channel selected by the user, recording may not be possible from the beginning of the program, but the time that can be stored in the first storage unit 118 can be extended compared to the case where all the channels are stored. When a recording instruction is given from the beginning of the program for a channel not selected by the user, the mobile terminal 101 is notified of the recording failure in S310 of FIG.

  In addition, in FIG. 3, the method of instructing recording while the user is watching TV on the mobile terminal 101 has been described, but the present invention is not limited thereto, and the channel and time the user desires to record using the input unit 103, Recording instructions may be given by inputting a program name or selecting from a list created from received program information. However, as shown in FIG. 3, by giving a recording instruction during viewing, the user can save the trouble of channel input.

  In S303, the mobile terminal 101 has extracted the start time of the program from the program information, but only the channel information is extracted, transmitted to the broadcast receiving device 111, and using the channel information received by the broadcast receiving device 111, You may make it extract the start time of a programme. Further, in place of the channel information, other information such as an identification code for identifying a program may be extracted and transmitted to the broadcast receiving device 111.

  In addition, when the data from the beginning of the program is not stored in the first storage unit 118 in S308, in the example of FIG. 3, only the recording failure is notified to the mobile terminal 101, but the user can record from the middle of the program. However, instead of notifying the recording failure in S310, a message such as "Program data at the beginning of the program is not stored. Do you want to continue recording from the middle of the program?" When a recording continuation instruction is received from the terminal 101, the process may proceed to S313, and the program data stored in the first storage unit 118 may be copied to the second storage unit 119.

  Also, if the program data file in the second storage unit 119 is full when receiving a recording instruction, or if the capacity becomes insufficient during recording, the mobile terminal 101 indicates that “the recording process is terminated due to memory over. Message "or the like" is sent to inform the user that the recording has been stopped. Instead of the message “end recording process”, a message requesting user selection as to whether or not to allow overwriting of the second storage unit 119 is transmitted, and program data is stored by overwriting according to the user's selection. It may be continued. In this case, the storage is not limited to the second storage unit 119, but may be temporarily stored in a storage memory of another channel of the first storage unit 118.

  When the second storage unit 119 receives a recording instruction from the mobile terminal 101 during the recording process, a message such as “cannot receive the recording instruction because it is currently recording” is transmitted. . When a recording instruction is input again from the user, the recording operation may be terminated and recording may be started with priority given to the recording instruction from the mobile terminal. At this time, it is preferable to transmit the message transmitted from the broadcast receiving device 111 including the channel or title being recorded. In this way, by telling the information of the program being recorded, the user may accidentally stop the recording even though the user has recorded an important program or a program that is more interesting than the program instructed to record. Can be prevented. When the second storage unit 119 can record a program of a plurality of channels at the same time, the above notification and processing are performed when the number of simultaneously recordable channels is exceeded.

  In S305, if the mobile terminal 101 is out of range in the communication network, the display unit 106 displays “Recording instruction failed because it is currently out of range of the communication network”. Thus, the user can know that the broadcast receiving apparatus 111 cannot be instructed to record, and can take measures such as storing only program data currently being broadcast on the mobile terminal 101, for example. Note that the recording instruction information may be automatically transmitted again when the mobile terminal 101 returns to the communication range.

  Next, a method for reproducing a program recorded in the broadcast receiving device 111 according to an instruction from the mobile terminal 101 will be described. FIG. 5 is a flowchart showing a process for displaying a list of recorded files on the display unit 116.

  The user inputs an instruction to display a recorded list via the input unit 103 of the mobile terminal 101. When receiving the display instruction transmitted from the mobile terminal 101 (S500), the broadcast receiving device 111 starts reading the management file in the second storage unit 119 (S501). It is searched whether there is management data after the current read point of the management file (S502). If there is management data, it is searched whether or not a flag is included in the management data (S503). If the flag is included, the program information is output to the display unit 116 (S504).

  If the flag is not included in the management data in S503, or after the program information is output to the display unit 116 in S504, the process proceeds to S504, and it is determined again whether there is management data after the current read point of the management file. Search for. In the example of FIG. 4, since the management data 410 is searched and the flag is stored in the area 408, after displaying the program information on the display unit 116, it is searched whether there is other management data in the management file. . If the management data 420 exists as in the example of FIG. 4, the process proceeds to S503. On the other hand, if no management data has been stored after the current reading point, it is determined whether or not program information has been output since the display instruction was received in S500 (S505). If no management data is stored in the management file, or if no management file with a flag is stored and no program information is output, the corresponding file such as "There is no recording designation file from the outside" (S506), and waits for input from the user (S507).

  When a recording file stored in the second storage unit 119 of the broadcast receiving device 111 is selected, there may be a file that has already been recorded in addition to the one recorded according to the recording instruction from the mobile terminal 101. . For this reason, if all the program information of the stored program is displayed, it may be difficult for the user to identify which program is instructed to be recorded from the mobile terminal 101. Therefore, as described above, when the user issues a list display instruction from the mobile terminal 101, only the program information of the program data recorded according to the recording instruction from the mobile terminal 101 is displayed, thereby improving the usability of the user. Can be improved.

  Although not shown in the flow of FIG. 3, when waiting for input from the user in S507, the user reproduces the program information displayed on the display unit 116 using the input unit 113. When the program data desired to be selected is selected, playback is started. At the time of reproduction, the program data of the program data file is read using the storage start address stored in the management file of FIG. 4 and converted into data that can be displayed on the display unit 116 by the decoding unit 115, and the control unit 117 To the display unit 116. For example, when the program of the management data 410 in FIG. 4 is selected, the address information in the area 406 is first read based on the header information in the area 404, and the corresponding program data is reproduced from the program data file. Next, the address information in the areas 405 and 407 is read out, and one program can be reproduced from the beginning to the end.

  In the example of FIG. 5, when it is determined in S505 that the program information has been output, the system waits for input from the user without notification (S507). However, the present invention is not limited to this, and the search is completed. A message indicating this may be displayed. As a result, the user can know that the search is finished and no new program information is displayed. In this example, the program information is output every time one piece of management data with a flag is searched. However, the program information may be displayed together after the search is completed.

  Further, when a recording instruction is given from the mobile terminal 101 to the broadcast receiver 111, the user may input a program category and display a recorded list using this category. For example, after a recording instruction is input from the user in S302 of FIG. 3, a message such as “Please enter a category” or “Please select a category. When the user inputs a character or number corresponding to the category displayed on 106, the category information input in S305 is included in the recording instruction information and transmitted. The category information may be extracted from the program information regardless of the user input. Then, the broadcast receiver 111 stores the category information in the management file of the second storage unit 119 together with other information such as a flag in S315. If a category is selected when the user inputs a recorded list display instruction in S500 of FIG. 5, whether or not there is category information corresponding to the management data is searched together with flag information in S503, and in S504. Display program information. There may be a case where a large number of program data stored by the recording instruction from the portable terminal 101 is stored in the second storage unit 119. Thus, by displaying only information of a predetermined category, the user can easily find desired recording data.

  If a playback instruction is transmitted from the mobile terminal 101 to the broadcast receiving device 111 without an instruction to display the list, the latest recorded program data recorded by the recording instruction from the mobile terminal 101 is automatically selected. You may make it reproduce | regenerate to.

  In addition, a list including not only recorded files but also files being recorded may be displayed. In this case, a mark indicating that the data is currently being recorded is displayed on the screen. When a reproduction request is made for a file being recorded, the address is read from the management file while writing to the second storage unit 119, and the corresponding program data is sent to the display unit 116 via the decoding unit 115. indicate.

  Next, a description will be given of a method of reproducing program data when selection of program data desired to be reproduced is input from the user in S507 of FIG. 5 or when a program data reproduction instruction is input without a list display instruction. To do. When such a program selection or playback instruction is input, the broadcast receiving device 111 starts playback from the beginning of the program data. This is because the mobile terminal 101 is instructed to record from the beginning of the program, and the user often desires to view the program from the beginning. However, depending on the user setting, a message for requesting user selection is displayed on the display unit 116, “Do you want to play from the beginning? Do you want to play from the beginning?”, And play from the beginning or from the beginning depending on the user selection. You may do it. When playback from the next is selected, the control unit 117 plays back the data broadcast after receiving the recording instruction. Also, the viewing point that the user desires to start recording is transmitted from the portable terminal 101 to the broadcast receiving device 111, stored as a part of the management data in the second storage unit 119, and the program data is reproduced from this viewing point. Anyway. Only when the user inputs such a viewing point, a message asking for user selection as described above is displayed. When there is no viewing point input, such a message is not displayed and the program starts. You may make it reproduce.
